Webb28 maj 2024 · The science goals of JWST require a versatile mid-infrared instrument covering the 5-28.5 μm wavelength range with a wide field of view for imaging through broad and narrow band filters, low resolution spectroscopy from 5-10 μm, moderate resolution spectroscopy with R ~ 3000, and high dynamic range coronography. Webb7 nov. 2013 · the Point Spread Function (PSF) is scaled with wavelength. One should expect it has multiple different polychromatic appearance depending on wavelength range and linearity of brightness transform. Here is example of polychromatic PSF in range 0.74-1.2um and monochromatic at 1um. Both PSF are logarithmic transformed brightness … bon for texas
